Patented Oct. 13, 1931 PATENT OFFICE BERT VANDERWILT, OF EVERETT,WASHINGTON DUST COLLECTING BAG FOR VACUUM SWEEPERS Application filedOctober 1, 1929. Serial No. 396,515.

My invention relates to improvements in dust collecting bags for vacuumsweepers, and it consists in the combinations, constructions and,arrangements hereinafter described 5 and claimed. 4

The purpose of this invention is to eliminate the objectionable andfilthy feature of cleaning the dirt and solids from the bag which isused to collect the dirt in devices such as vacuum cleaners, cleaners,sanding machines, planers, saws, stone polishers, etc. The dirt andsolids are collected in a separate collecting bag which is removable andwhich may be thrown away, thus obviating one thrown away. I providenovel means for pprmitting the full bag to be tied into a'pac age uponremoval from the largebag, whereupon it may be burned or otherwisedisposed ofz A further object of my invention is to provide a device ofthe type described which is extremely simple in construction and whichis durable and eflicient for the purpose intended.

Other objects and advantages will appear as the specification proceeds,and'the novel features will be particularly pointed out in the claimshereto attached. K

My invention is illustrated in the accompanying drawings, in which: I 3

Figure 2 is a section along the line 2-2 of Figure 1,

Figure3- is a section along the line 3-3 of 'Fi re2,and

igure 4 is a perspective view of one of the refuse bags. 7

' In carrying out my invention, Imake use of a vacuum sweeper indicatedgenerally at 1. A dirt conveying conduit 2'leads from the sweeper 1 andenters a main bag 3. In

Figure 3 I show the conduit or'tube 2- as having a collapsible end 4.This end closes the upper end of the tube 2. when the sweeper stopsfunctioning. This prevents the dirt and solids from falling back intothe tube andbeing conveyed back into the blower in the shaking of themain dust bag which is .now the practice. A new bag replaces the terial.

main bag 3 by means of the tube 2. The

neck of the refuse bag is held open by a fiber collar 9 disposed in theoutlet 6.

It will be seen from Figure 1 that the lower portion of the main bag 3may be opened in order to gain access to the refuse or collectmg; bag 5.I have shown azipper 10 for closing and opening the portion of the mainbag disposed adjacent to the refuse bag 5.

From the foregoing description of the various parts of the device, theoperation thereof may be readily understood. I

A collecting bag 5 is secured to the outlet 6 by the string 8, and thedevice is ready for use. A good part of the dirt collected in the mainbag 3 will drop into the refuse bag 5.

, In removing the bag 5, the operator opens the-lower portion of themain bag 3 by means of the zipper 10 and then shakes the main ba 3 forcausing all of-the dirt to enter the re use bag. The string 8 may now beuntied 80.

in order to remove the refuse bag and then means of the same string ifdesired, as shown in Figure 4:. I

A new collecting bag 5 is secured to the outlet 6 by strings 8, and themachine is ready for further use. It will be seen that the shaking ofthe bag in the open air is obviated, nd there is no muss in handling therefuse bag 5 because it is made-of a non-porous ma- The device isextremely simple in construction, and can be adapted to uses other thanfor vacuum sweepers.

Although I have shown and describedone 95 embodiment of my invention, itis to be understood .that the same is susceptible of various changes,and I reserve the right to employ such changes as may come within thescope of the invention as claimed. 10

I claim: 1. In combination, a dust collecting bag, a conical-shapedpartition disposed in said bag, a non-porous refuse bag removablysecured a to the open end of the partition for receiving dirt from themain bag, a conduit for delivering dirt to the main bag at a point abovethe partition, said conduithaving a flexible end portion extending abovethe artition, and w means for opening the main agbelow the a partitionfor gaining access to the non-porous ag. t 2. In combination, a'dustcollecting bag,

conical-shaped partition disposed in said bag, a refuse bag removablysecured to the open end of the partition for receiving dirt from themain bag, a conduit for delivering dirt to the main bag at a point abovethe partition, said conduit having a flexible end portion extendingabove the partition, and means for opening the main bag below thepartition for gaining access to the non-porous bag.

3. In combination, a main bag, a partition disposed in the bag, a dirtconveying conduit for conveying material above the partition, and arefuse bag removably secured to the outlet end of the partition, saidconduit having a flexibleend portion extending above the partition. BERTVANDERWILT.
